I am unsure how to do the conversions

Ex5: arcminute 1 arcmin = 1/60 deg = rad Ex6: arcsecond 1 arcsec = 1/60 arcmin = rad Ex7: liter IL cm my3 Ex8: ounce (mass) 1 ozm = 28.35 gm Ex9: pound (mass) 1 Ibm = 16 ozm = g kg Ex10: ton 1 t ~ 2000 1b (mass) = kg Ex11: angstrom 1 A = 10 m = cm Ex12: inch 1 in = 2.54 cm = m Ex13: foot 1 ft m cm Ex14: meter 1 m in Ex15: gallon 1 gal = 231 in' = cm cmEx16: Acceleration due to gravity g = 9.80665 m/s' = ft/s Ex17: pound (force) 1 1bf = m . g= kg . m/s' = N Ex18: Newton IN Ibf Ex19: Torque (F . d) 1 1bf . ft (pound-feet) = N . m 2. Determine the SI units of each of the following quantities. Ex20: volume = Ex21: density = Ex22: pressure = Ex23: energy = 3. Ex24: Fingernails grow approximately 0.8"/year. What is their growth in ft/sec
